摘要: Abstract A pore-scale numerical method for simulating multiphase granular media is described, in which the solid skeleton represented by a dense random packing of poly-disperse spherical particles and pore space discretized as network pores. The underlying idea to build an efficient analyzing hydro-mechanical behavior such materials. We design model specifically quasi-static primary drainage, using criterion displacements invading fluid expressions forces exerted on grains fluid’s pressure surface tension. can reproduce some features including phase entrapment capillary fingering. illustrate simulated drainage oedometer conditions, highlighting deformation induced partial saturation.
